GraphEdit
=========

**Inherits:** :ref:`Control<class_Control>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

GraphEdit is a control responsible for displaying and manipulating graph-like data using :ref:`GraphNode<class_GraphNode>`\ s. It provides access to creation, removal, connection, and disconnection of nodes.

Description
-----------

**Note:** Please be aware that this node will undergo extensive refactoring in a future 4.x version involving compatibility-breaking API changes.

GraphEdit provides tools for creation, manipulation, and display of various graphs. Its main purpose in the engine is to power the visual programming systems, such as visual shaders, but it is also available for use in user projects.

GraphEdit by itself is only an empty container, representing an infinite grid where :ref:`GraphNode<class_GraphNode>`\ s can be placed. Each :ref:`GraphNode<class_GraphNode>` represent a node in the graph, a single unit of data in the connected scheme. GraphEdit, in turn, helps to control various interactions with nodes and between nodes. When the user attempts to connect, disconnect, or close a :ref:`GraphNode<class_GraphNode>`, a signal is emitted in the GraphEdit, but no action is taken by default. It is the responsibility of the programmer utilizing this control to implement the necessary logic to determine how each request should be handled.

\ **Performance:** It is greatly advised to enable low-processor usage mode (see :ref:`OS.low_processor_usage_mode<class_OS_property_low_processor_usage_mode>`) when using GraphEdits.

.. rst-class:: classref-method

:ref:`bool<class_bool>` **_is_in_input_hotzone** **(** :ref:`Object<class_Object>` in_node, :ref:`int<class_int>` in_port, :ref:`Vector2<class_Vector2>` mouse_position **)** |virtual|

Returns whether the ``mouse_position`` is in the input hot zone.

By default, a hot zone is a :ref:`Rect2<class_Rect2>` positioned such that its center is at ``in_node``.\ :ref:`GraphNode.get_connection_input_position<class_GraphNode_method_get_connection_input_position>`\ (``in_port``) (For output's case, call :ref:`GraphNode.get_connection_output_position<class_GraphNode_method_get_connection_output_position>` instead). The hot zone's width is twice the Theme Property ``port_grab_distance_horizontal``, and its height is twice the ``port_grab_distance_vertical``.

This virtual method can be used to insert additional error detection while the user is dragging a connection over a valid port.

Return ``true`` if the connection is indeed valid or return ``false`` if the connection is impossible. If the connection is impossible, no snapping to the port and thus no connection request to that port will happen.

In this example a connection to same node is suppressed:

Create a connection between the ``from_port`` of the ``from_node`` :ref:`GraphNode<class_GraphNode>` and the ``to_port`` of the ``to_node`` :ref:`GraphNode<class_GraphNode>`. If the connection already exists, no connection is created.

Removes the connection between the ``from_port`` of the ``from_node`` :ref:`GraphNode<class_GraphNode>` and the ``to_port`` of the ``to_node`` :ref:`GraphNode<class_GraphNode>`. If the connection does not exist, no connection is removed.

----

.. _class_GraphEdit_method_force_connection_drag_end:

.. rst-class:: classref-method

void **force_connection_drag_end** **(** **)**

Ends the creation of the current connection. In other words, if you are dragging a connection you can use this method to abort the process and remove the line that followed your cursor.

This is best used together with :ref:`connection_drag_started<class_GraphEdit_signal_connection_drag_started>` and :ref:`connection_drag_ended<class_GraphEdit_signal_connection_drag_ended>` to add custom behavior like node addition through shortcuts.

\ **Note:** This method suppresses any other connection request signals apart from :ref:`connection_drag_ended<class_GraphEdit_signal_connection_drag_ended>`.

\ **Warning:** This is a required internal node, removing and freeing it may cause a crash. If you wish to hide it or any of its children, use their :ref:`CanvasItem.visible<class_CanvasItem_property_visible>` property.
